IMPROVED SHOE-NAIL.

The Schedule referred to in these Letters Patent and making pariof the same.

To all whom it may concern:

Beit known that l, H. l?. WHIDDEN, of South Abington, in the county of Plymouth, and State ofMas sachnsetts, have invented an Improved Shoe-Nail; and I do hereby declare thatthe following, taken in connection with the drawings which accompany and form part of this specieatiomis a description of my invention, sufficient to enable those skilled in theart to m'actise itV in one use of nails, as means for uniting the solesv and vamps of boots and shoes, there have of late been employed, to a greater or less extent, sprigs or sections oi' wire, (sometimes headed, sometimes .ponted, and sometimes uniform throughout the length of each,) with jagged, serrated, or corrugated sides or edges, or

with screw-threads cut around the shanks, every such nail having its holding-power increased by reason of this formation of its sides or edges.

My invention relates to the manufacture ofnails of this class, thel invention consisting in a eut shoe-nail, having a taperingshauk, 'a round 'or frusto-conical head, and serrations upon the body of the tapering shank, from the. head down to, or nearly to the point; a nail having these combined features, having holding-power, ease of entrance, capability of clinching at its point, and finish at its head, beyond any shoe-nail hitherto made.

.Lhe drawings represent a nail embodying my invention.

A shows a side view.

B, an edge view.

C, a view of the had.

D, an end view lodkrng at the point.

a denotes the shank,`

b, the head.

c, the point.

d', the serrationf- 1n the .manufact ure of the improved nails, the blanks are cut from a plane, as in ordinary eut-nail manufacture, the plate beii vbrated or turned, (or the cutter vib1ated,) or two ci ters, set at di'erent angles, being used, to cut the nails alternately, heads and points. After each blank .s' thus cut to a tapering form, the shank is grasped between a pair of grooved jaws, at one. end .of each'. ol'whtehgmoves is a eountersunkerecess, and a header then advances and upsets the metal at the large end of the blank, forming the head 11, in the conical recess made by the countersink at the end of the two grooves, the head being thereby made round and fusto-conical, as seen in the drawings.

Throughout each jaw-groove are small teeth, which, when the jaws grasp the shank, indent the body of the shank, as seen in the drawings.

rl`he nail-shank has a uniform thickness throughout, due to the thickness of the plate from which it is cut, but in width it tapers from the head to the point, the point being cut quite thin, as seen at B, so that it will readily clinch when driven against an iron-bottomed last.

By the use of these nails, the serrations and the heads both secure the outer sole from drawing olf, the clinched points prevent the nails from drawing out, and the round heads impart a finish to the surfaces of the soles, into and flush with which the heads are sunk by driving.

-I claim an improved -cut shoe-nail, having a round fusto-conical head, a tapering shank, and serrated corners or edges, substantially as shown and described. H. F. WHIDDEN. Witnesses:
